Aye up mate. Some stuff doesn't get replied to that quick, no reply within 4 hours is kinda normal when it's something relatively rare like 338 win mag.
I'm not reloading for 338 win mag but I do reload. It doesnt matter too much what you're reloading, all the kit needed is the same.
Do you have a specific query or problem?
Or were you meaning what brass, bullets, powder etc?
